The family moved to Kenya where Peter Davies taught and was chaplain at the Prince of Wales (later Nairobi) School for 13 years.

[4] After studying philosophy and psychology at the University of Oxford from 1979 to 1981, Davies spent two years in the merchant navy.

He subsequently undertook medical studies at Queen's University Belfast, graduating MB BCh BAO in 1988.

[7][8][9] Davies saw a job advertisement for a medical officer in the Falkland Islands, and in July 1996 he and his wife sailed from Britain on their 36-foot steel yacht, Cowrie.

After visiting the Azores, the Canary Islands, Cape Verde, and Brazil, they arrived in the Falklands in February 1997, and settled in the capital, Stanley.

[7][9] Davies' work as a medical officer included general practice, emergency medicine, evacuations and looking after in-patients at the hospital.

The claim that the people of the Falkland Islands had no political rights was unjust and contrary to the principles on which the United Nations was based.

[16] From 2014, Davies worked as a general practitioner at the Calder Medical Centre, part of the Auckland City Mission, providing care to vulnerable communities including the homeless and people dealing with mental health and addiction issues.
